Rotor for dual-excitation electrical rotating machine with independent magnets, uses magnets of alternating polarity distributed round rotor periphery to face magnetic end plates

摘要

The electrical machine has two annular end plates (30,32) made of a magnetic material, placed coaxially with the rotor shaft. Between the end plates a succession of magnets are distributed round the periphery of the rotor (4) forming a sequence of magnetized zones of alternating polarity. Each magnet is formed from an independent component (44) which is fixed (46) to the rotor.
